  • Description
  • Based on Silicon Lab's si4432 chip, our company has developed three modules with different package sizes: RF4432PRO, RF4432 and RF4432X1 to meet the needs of different customers. We recommend that customers choose the RF4432PRO module with the best anti-interference performance. These modules all have extremely low receiving sensitivity (-121 dBm), coupled with the industry-leading output power of +20 dBm to ensure extended range and improved link performance.
  • RF4432PRO modules use lead-free technology for production and testing strictly, and comply with RoHS and Reach standards.

RF4432PRO Pin Definition

 

Pin NO. Pin Name Description
1 GND Power ground
2 GPIO0 The control pin of the transmitter switch is connected inside the module
3 GPIO1 The control pin of the transmitter switch is connected inside the module
4 GPIO2 Connect directly to the GPIO2 pin of the chip
5 VCC Positive power supply 3.3V
6 SDO 0~VDD V digital output, provides serial readback function to internal control register.
7 SDI Serial data input. 0~VDD V digital input. This pin is a 4-wire serial data serial data stream bus.
8 SCLK Serial clock input. 0~VDD V digital input. This pin provides a 4-wire serial data clock function.
9 nSEL Serial interface select input pin. 0~VDD V digital input. This pin provides select/enable function for 4-wire serial data bus. This signal is also used to indicate burst read/write mode.
10 nIRQ Interrupt output
11 SDN Chip enable pin. 0~VDD V digital input. SDN=0 in all modes except shutdown mode. When SDN=1, the chip will be completely shut down and the contents of the register will be lost.
12 GND Power ground
13 GND Power ground
14 ANT Connect with 50 ohm coaxial antenna
